Neues Starterkit: Wetterstation


Recommended Posts

500mA würden Problemlos reichen. Das Problem ist, dass die ersten Raspberry Pi Versionen nur 100mA lieferten:


Originally the on-board USB ports were designed for USB devices using one "unit load" (100 mA) of current. Devices using more than 100 mA were incompatible with the Raspberry Pi, and for them a self-powered USB hub was required. However, due to user feedback, the RPF, at the end of August 2012, decided to remove the USB polyfuses which largely caused this behaviour. However, the maximum current that can be delivered to a USB port on these modified boards is still limited by the capabilities of the power supply used, and the 1.1 A main polyfuse. Also a disadvantage of the current way the modification is done is that its no longer possible to hot-plug USB devices directly into the PI, when hotplugging is necessary it can be done in a hub.


Also je nachdem welche Version du hast funktioniert es. Wenn du die neuere Version ohne die USB-Sicherung hast, geht allerdings hotplug nicht... ;D
